Answer:
A: All sides are congruent
Step-by-step explanation:
If all sides were congruent then it would be a square.

Answer:
If XY = -1 then Y = -1 / X
Substitute the given values of X into the above formula and solve for Y:
X = 1 ⇒ Y = -1
X = -1 ⇒ Y = 1
X = 1/2 ⇒ Y = -2
X = -1/2 ⇒ Y = 2
X = 1/3 ⇒ Y = -3
X = -1/3 ⇒ Y = 3
Additional points:
X = 2 ⇒ Y = -1/2
X = -2 ⇒ Y = 1/2
If X = 0 then Y = 1/0 which means the function is undefined, therefore the curve will get close to Y = 0 (y-axis) but will not touch it.
If Y = 0 then 0 = -1/X which is impossible, therefore the curve will get close to X = 0 (x-axis) but will not touch it.
Problem 4:
multiply by 11,
8(n-10) = 64*11
divide by 8,
n-10 = 8*11
Add 10,
n = 88 + 10 = 98
--------------------------------------------------------
Problem 5:
-0.6(r+0.2)=1.8
Divide by -0.6,
r+0.2 = -3
subtract 0.2,
r = -3 - 0.2 = -3.2
--------------------------------------------------------
Problem 6:
I hope this method isn't too confusing for you,
but I would multiply through by the LCM of the denominators to get rid of the fractions. LCM of 3, 9 and 5 is 45.
Multiply both sides by 45,
(45w - 20)(-30) = -36
Divide -30,
45w - 20 = 36/30
Add 20,
45w = 36/30 + 20
Divide 45 as a final step,
w = 21.2/45
Answer:
Point N will be located between 0 and -1.
Step-by-step explanation:
Points A and D are placed at (-4, 0) and (4, 0) on a number line.
We have to find the location of a point N which divides AD in the ratio of 3 : 4.
Coordinates of a point (x, y) which divides a segment with extreme ends at and in the ratio of m : n is given by,
x =
y =
By this formula, coordinates of the point N will be,
x =
x =
y = 0
Therefore, coordinates of the point N are .
Point N will be located between 0 and -1.
